The most important things that college teaches is how to set long-range goals, stick with them, and manage time so that you get everything done when you have a lot of competing priorities. It's the hardest thing you will learn, at least it was for me. If you get behind in a semester, it is a bitch to ever catch up, and usually you won't. So plan ahead and keep up. Get started on everything earlier than you think you hvae to.
